Barrier Spongepan is one of the most common products used in sound insulation. Spongepan is a sound insulation material that can meet your demands in any environment, with thicknesses ranging from 10mm to 50mm and density options ranging from 100dns to 200dns.
In order to use the sound-cutting sponge panel at the highest efficiency, the material thickness and density are determined according to the current sound level in the environment. Depending on the need, it can also be used by laminating a sound barrier to one side of the sound-cutting sponge or between two sponge panels. Spongepan laminated with a barrier is known as 'Barrier Spongepan'.
The difference from Bondexpan is that its raw materials vary, but the sound insulation rate is the same.
